Uses of nickel:

1. It is mainly used in electroplating industry. Nickel plated articles are beautiful, clean and not easy to rust;

2. Nickel is widely used in the manufacture of alloys, which can improve the mechanical strength;

3. Nickel is magnetic and can be attracted by magnets. It can be used to make electromagnetic cranes;

4. Nickel contains salt. After oxidation, it can be used to make iron nickel alkaline battery.

Nickel is a chemical element and a raw material, which is also widely used in our daily life. Maybe you don't know and understand it very well. Let's introduce the use of nickel in detail.

Metal nickel is mainly used in electroplating industry. Nickel plated articles are beautiful, clean and not easy to rust. Very fine nickel powder, commonly used as catalyst in chemical industry.

Nickel is widely used in the manufacture of alloys. Adding nickel to steel can improve mechanical strength.

Titanium nickel alloy has the ability of "memory", and the memory is very strong. After a long time, it is accurate for tens of millions of times. Its "memory" ability is to remember its original shape, so people call it "shape memory alloy".

Nickel is magnetic and can be attracted by magnets. Alloys made of aluminum, cobalt and nickel are more magnetic. When the alloy is attracted by the electromagnet, it will not only be sucked by itself, but also hang something 60 times heavier than it under it without falling down. In this way, it can be used to make electromagnetic crane.

Nickel salts are mostly green. Nickel hydroxide is brown black and nickel oxide is gray black. Nickel oxide is often used to make iron nickel alkaline batteries.
